I see Dr Filler in Santa Monica, Ca this is where his primary office is located. I had my neurography done in Pasadena, Ca.
I don't believe he has a satellite office although you could call his Ca office and inquire 310-314-6410.
The scan is done in Norristown and then he most likely reads it from Ca. I would think if you called the neurography center they could answer your question. I wish I could answer more for you. I know how it is with controversial it is the same way here in good ol Southern California.
Many Hugs and Good Luck
